Related to secondary structure: secondary structure RNA

sec·on·dar·y struc·ture

the localized arrangement in space of regions of a biopolymer; often these types of structures are regular and recurring along one dimension, for example, the α-helix often found in proteins.

secondary structure

n.
The three-dimensional structure of the polypeptide backbone of a protein (such as alpha helix, beta sheet, and coil patterns), or the sugar-phosphate backbone of a nucleic acid (such as the double helix pattern of DNA).

It is thus reasonable to expect that this fact is reflected by a variable secondary structure. In fact, secondary structure pattern changed considerably not only with absorbed dose but also with time (Figure 10).
